ROllerozxa 462369618e Turn TMS_USE_GLES compile-time option into a runtime use_gles setting
This of course requires support from the SDL library Principia is linked to, but should still make it more accessible to switch between the two on Linux

Principia Open Source Project

Principia

Principia is a sandbox physics game originally released in November 2013. It is the successor to the 2011 Android hit game "Apparatus". In August of 2022 Principia was released as open source, and is now being developed as an open source project by the Principia community.

Principia runs on anything with a recent enough version of Windows, Linux or Android. Experimental ports to Haiku OS and macOS are also available, and work to port Principia to other platforms are very welcome.

Binary builds

Release builds builds of Principia for Windows, Android and Linux are available on the download page.

There are also nightly build artifacts that get automatically built by GitHub Actions CI on each commit and are available for download, see Nightly Builds on the wiki.

Getting involved

Feel free to fork this project and send in your pull requests. This is a community project and the community decides how the project evolves.

For a brief overview on how to get started with contributing to the game, see the Contributing to the Game page on the wiki.

Also be sure to follow @principia on Mastodon for more updates about the project.

Building from source

See Compiling Principia on the wiki for building from source on supported platforms.
